Adventures of the Thing #1 (April 1992), art by Sam Kieth
Two-in-One Thing (Ugh *shudder* That sounds so dirty. Its right up there with "Giant Size Man-Thing") Anyway, Two in One is my personal fav here. The object that Thing #1 is carrying in this cover draws your eye straight from the logo and directly into the action. We get a sense that what he is carrying has shape and weight and could hurt if he hurled at his opponent, which is himself! DUN-DUN-DUH! Both their poses are dynamic, with the arms stretched out in front of them and, giving us depth and energy for what could very well be The Sparring Match of the Century.
Adventure Thing just looks like he's ticked that someone's watching him while he's trying to take a dump.
Though I do admit I like the pun tagline of Adventure Thing with "If its not one thing... Its another!", and suggests a more comedic tone than the story itself actually delivers.
